Page 6: Charging Your Sciplus-2200
Charging your SciPlus-2200 Charging the calculator is easy. Simply plug the USB wall charger into a regular outlet, and plug the USB cable into the SciPlus-2200. The calculator will receive a good charge overnight. The SciPlus-2200 will operate for many weeks between charges. Note that, if you regularly use the backlight, the battery will deplete much more quickly. This is not a problem; just charge it up and you’re good to go. Your SciPlus- 2200 calculator includes a USB Wall Charger and cord. Please ensure that these items are in the box. When the SciPlus-2200 is charging, you will notice the battery symbol is animated. The battery is completely charged if, with the charger still plugged in, you turn on the battery and the animation shows three bars. Note: If your SciPlus has been unused for a long time, you may need to charge it for a while before it will even turn on. When this happens, make sure you “RESET” the SciPlus by carefully inserting a paperclip into the hole on the back of the calculator. This restores factory settings to ensure proper operation.

Page 8: Sciplus-2200 Operations
SciPlus-2200 Operations The SciPlus-2200 follows the “BEDMAS” rule for order of operations: Brackets è Exponents è Divide è Multiply è Addition è Subtraction Most of the SciPlus-2200 keys have two functions. The lower function appears in a white font. The alternate, or 2 function, when present, appears in a yellow font. To access this function, the 2 key must first be pressed. Throughout the key descriptions below, if a key symbol appears in a yellow background, this indicates that the 2 key must be pressed before this key is pressed. -
Page 9: Adjusting The Display Contrast
SciPlus-2200 Scientific Calculator – User Guide Adjusting the Display Contrast There is a dial on the right hand side of the SciPlus-2200 that you can use to adjust the contrast of the display. Note that this does NOT adjust the brightness of the backlight; that is done through the settings menu. You may find that adjusting the contrast will help maintain optimal visibility of the display as the battery depletes. Soft Keys The keys labeled A , B , C and D do not have a specific function. Instead, labels at the bottom of the display define the function of these keys. If there are no labels, these keys will not do anything. You will use these keys when adjusting the SciPlus-2200’s settings, and for memory and statistics operations. Working with Previous Results When entering expressions in the bottom line, it’s very easy to use the results of previous calculations displayed in the lines above it. Using the ç and è arrows, position the cursor at the location in the expression where you wish to insert a previous result. Now, using the é and ê arrows, select the previous result that you wish to insert into the current expression, and press ↵... -
Page 10: Auto Shutoff
Auto Shutoff Your SciPlus-2200 calculator will automatically shut off after five minutes of inactivity. Many of the calculator’s current settings such as the angle mode, number format, etc., will be saved, so that it will turn on again in the same state. Values stored in memory and the statistics table are also saved. Note that if the backlight is on when the calculator is turned off, it will be off when the calculator is again turned on. If the calculator is left off for an extended period (typically many weeks), these settings will be lost. Page 6 of 23 version 1.6... -
Page 11: Settings
SciPlus-2200 Scientific Calculator – User Guide Settings There are three settings screens in the SciPlus-2200, accessed by the key. Cycle through the settings screens using the é and ê arrows, or by entering 1, 2 or 3. Change settings in any of the screens using the A - D soft keys. Number Format NUM FORMAT There are four number formats supported by the SciPlus-2200: Standard: Numbers show up to ten-digit precision. 4 5 6 7 Examples: 101, 41250.5, 0.33333333 Fixed Notation: Number of decimals is fixed. Examples: 101.00, 41250.50, 0.33 Scientific Notation: Numbers are displayed in powers of ten, with a fixed number of decimals. Examples: 1.01E+02, 4.13E+04, 3.30E-01 Engineering Notation: Numbers displayed in powers of … 10 , 10 , 10 , 10 …, with fixed decimal precision. - Page 12 Backlight: BACKLIGHT Use the A and B soft keys to turn the backlight on/off. The C and D keys adjust the brightness. Note that the backlight will significantly shorten the duration of a battery charge from weeks to hours. For this reason, the SciPlus- 2200 always powers on with the backlight turned off. INVERT Screen Inversion: Often, people with low vision are able to benefit from an inverted screen. The A and B keys simply invert the display between black/white and white/black.

Page 26: Troubleshooting
Troubleshooting Battery does not recharge: The SciPlus battery may fully discharge after a month or more of inactivity. Simply plug in the calculator as if to recharge, for about half an hour. Next, perform a reset by inserting a paper clip into the small hole on the underside of the calculator, and gently push until you hear/feel a small click. Then keep the calculator plugged in at least overnight to fully recharge. If a reset does not resolve the problem, determine whether it is an issue with the USB charger or cord by attempting to recharge with another USB charger and /or cord. SciPlus calculator is acting erratically: Perform a reset by inserting a paper clip into the small hole on the bottom left of the underside of the calculator, and gently push until you hear/feel a small click. The SciPlus is not working (screen is blank or black): It may appear to not be working, but in fact the contrast is set too low or high. Adjust the contrast wheel on the right edge of the calculator.
